To @ZZ whoml t may col/boerin.4

Be it known that I, JERRY D. DECELLE, a citizen of the United States, residing at Fort Collins, in the county of Larimer and Statev of Colorado,` have invented a new and useful Nippers or Hoof-Trimmer, of which the following is a specification. f.

This invention relates to nippers or hooftrimmers, and has for its objectto increase the power of such implements and ,to provide` an improved adjustable cutting or trimming plate, whereby the trimming action may be effectively adjusted.

To these ends the present invention consists in the combination and arrangementjof parts, as will be hereinafter more lfully described, shown in the accompanying drawings, and particularly pointed out in the ap-k pended claims. v

In the drawings, Figure 1 isa perspective view of the improved implement. Fig. 2 is a longitudinal sectional view taken in the plane of the implement. Fig. 3 is a similar View taken on the line .fr 41:, Fig. 2.Y Fig. 4 is' an underneath perspective view of the cutting-plate.

Corresponding parts are designated by like reference characters in all the figures of the drawings. l i

Referring to the accompanying drawings, 1 designates a pair of operative levers whichl are bifurcatedlongitudinallyat the inner ends and in the planepof the levers. At thebifurcated ends fof the levers each side thereof is' provided with an inwardly-extending Vor offset bearing-eye 2, and the latter are connected together by means of a suitable pivot-"pin or, bolt 3, the latter being provided with a sleeve 4, fitting snuglyf between the adjacent eyes,L so as to properly space the same apart.

A pair of auxiliary levers' have their outer. ends pivoted, as at 6, within the respective bifurcations of the operating-levers and extend longitudinally beyond the pivoted ends of the said levers. One of vthese-levers is provided with a longitudinal,bifurcation '7, located beyond the end of the operating-levers, and the other lever 'passes loosely through said bifurcation and is pivoted therein by means of a pivot-pin. The' outer ends of the jaws of the auxiliary levers areeach pro- Ivided with a athead 9, having at its outer 'end a shoulder 10, extending the entire Width of the head and at right angles to the plane `of the levers. Fitted to one of these heads isa cutting or trimming plate 11, having an inclined cutting edge 12 and provided upon vits under face with a transverse shoulder 13,

adjacent to the cutting edge. This plate is arranged fiat upon the head, engaging against `the shoulder l0 and having the shoulder 13 `engaging against the inner edge of the head and removably connected thereto by suitable screw-fastenings 14,. In order that the cut- Iting-plate maybe,adjusted,-l provide an adl justingscrew 15, fitted in a countersunk `threaded opening 16, provided in the outel face of the head intermediate of the sides and adjacent to theshouldered end thereof. The plate is provided` with a smooth opening 17, countersunk upon its under face, alined with the adjusting-screw, and smaller in diameter than the head of the same. Thus it will be understood that the opening 17 exposes the head ofthe adj ust-ing-screw 15 through the cutting-plate, whereby the ,screw may be adj usted to give the plate more or less incline, so as to regulate the cutting action thereof. The opposite head 9 is provided with a removable guard-plate 18, beneath which the cutting-plate is adapted to pass in the operation of the implement.

Adjacent to the base of the longitudinal bifurcation each of 'the operating-levers 1 is provided with an enlargement or shoulder 19 upon its inner face, and to one of these shoulders is connected a rubber stop 2O by means of a suitable screw21, 2v hereby the levers are limited in their movement and are prevented from striking together and thereby producing an unpleasant noise.

By reason of the fact that the auxiliary levers are pivoted at their ends 'within the longitudinal bifurcations formed in the operating-levers said auxiliary levers are gradually drawn into the bifurcations as the operatinglevers are pressed together, thereby supporting lthe auxiliary levers andeifectively preventing any lateral movement thereof. The sleeve Il, carried by the pivot-pin 3,4 is adapted to prevent the opposite sides of the respec- -tive operating-levers from binding upon the auxiliary levers, so that the implement may work easily and electively.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacri- {icing any of the advantages of this invention.

\V hat I claim is- 1. An implement of the class described, comprising a pair of operating-levers bifurcated longitudinally at the pivoted or hinged ends thereof, and a pair of auxiliary levers having cutting or trimming jaws, said auxiliary levers being pivoted within the respective bifurcations of the operating-levers and adapted to be received longitudinally within said bifurcations as the operating-levers are forced together, substantially as and for the purpose set forth.

2. In an implement of the class described, the combination with a pair of operating-levers bifurcated longitudinally at their inner ends, the latterbeing provided with inwardlyotlset bearing-eyes, a pivot-pin pivotally connecting said eyes, and a sleeve encircling the gether, substantially as and for the purpose set forth.

3. In an implement of the class described, the combination with a pair of levers having a pair of jaws, of an adjustable cutting or trimming plate having an opening formed therethrough and fitted to one of the jaws, a screw carried by the said jaw and accessible through the opening in the plate, whereby the screw may be adjusted to regulate the inclination of the cutting-plate, substantially in the manner shown and described.

4. In an implement of the class described, the combination with a pair of operating-levers having a pair of jaws, of a cutting or trimming plate carried by one ofthe jaws and provided with a smooth opening countersunk upon its inner face, and a screw adjustable in the countersunk screw-threaded opening provided in said jaw, the opening in the plate being smaller than the head of the screw and alined therewith so as to expose the screw and permit of the same being operated to adjust the inclination of the plate, substantially in the manner shown and described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

JERRY D. DECELLE.
